Differential assembly with self-lubricating function

Abstract

The invention belongs to the technical field of automobile accessories, and particularly relates to a differential assembly with a self-lubricating function. The technical problems such as short service life in the prior art are solved. The differential assembly with the self-lubricating function comprises a differential shell, half-axle installation channels are arranged at the two ends of the differential shell correspondingly, half-axle gears are arranged in the half-axle installation channels correspondingly, a planetary gear axle is fixedly arranged on the differential shell, planetary gears engaged with the half-axle gears are arranged at the two ends of the planetary gear axle correspondingly, the differential shell comprises a first shell and a second shell, the first shell is provided with at least two first arc-shaped gaps, second arc-shaped gaps corresponding to the first arc-shaped gaps one to one are formed in the second shell, each half-axle gear comprises an axle body and a bevel gear fixedly arranged at one end of the axle body, the axle bodies are arranged in the half-axle installation channels in a penetrating mode, and a self-lubricating structure is arranged between the axle bodies and the half-axle installation channels. The differential assembly with the self-lubricating function has the advantage of long service life.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a differential gear assembly with a self-lubricating function. Background technique [0002] The power of the car engine is transmitted to the drive axle through the clutch, transmission, drive shaft, and then distributed to the left and right axle drive wheels. In this power transmission path, the drive axle is the last assembly, and its main components are reducer and differential. Differential A differential mechanism that transmits rotational motion from one shaft to two shafts and enables the latter to rotate at different speeds relative to each other. Usually consists of gears. The differential on automobiles and tractors is located in the rear axle and consists of a differential case, planetary gears and side gears; the automobile differential is the main part of the drive axle. Its function is to allow the two half shafts to rotate at different speeds while transmit...

AI Technical Summary

Problems solved by technology

The existing automotive differentials are not easy to assemble and produce (especially the split differential case), and the production efficiency is low. In addition, after a long period of use, the friction coefficient between the side shaft gear and the differential case Larger, that is to say, the lubrication effect between the side shaft gear and the differential case is poor, which invisibly shortens the service life of the differential
